Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Required relays included.
Features:
Installation
This custom-fit T-One connector plugs into your vehicle's 12-pin wiring harness located behind the passenger's-side kick panel.
Once you've plugged in the 12-pin connector, plug the 4-way harness in beneath the vehicle, behind the driver's side rear bumper
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

This kit has exactly what my 2015 frontier needed. The pieces are good quality and everything for exactly as it should. The instructions were accurate and I was able to install everything, but some steps were a little vague and a couple of additional pics would have made them more clear. Additionally, a mounting bracket for the trailer connector would be a great addition.
Everything came as planned. The wiring harness worked perfect. The video made it very simple.
Wiring harness fit my Nissan Xterra perfectly. Took about 15 minutes to hook everything up and the trailer lights all work as expected. Very happy with the harness, relays, and trailer connector.
Connects perfectly with the stock wiring. Looks factory. Good product to have if your Xterra didn’t come with a tow package
Excellent product. The installation process couldn't be easier.
This was not listed as an exact fit but worked perfect with my 2024 Nissan Frontier. It all plugged into the factory wiring. Made for a very easy instillation.
I received my hitch and wiring harness kit for my 2019 Frontier within a few days after ordering. The items were well packaged, and nothing was damaged. The install instructions/video on your website were spot on. I had the whole thing installed and ready to go in less than an hour. Fit and finish of the etrailer hitch is very nice for the price. I would definitely recommend etrailer.com to others.
This wiring harness plugged in and the install only took about 15 minuites start to finish. It worked great!
Easy installation... the online videos really helped.
I had an existing harness that was installed with the hitch and the running lights were not working and the shop couldn't figure out the problem!
I removed the passenger side panel and saw the relays were missing. I decided to just tackle the fix myself and it worked out great.
Great product! Wish I'd bought this first.
I wasted alot of time trying to get running lights on my Nissan Xterra pigtail. I had brake and turn signal only. Excellent customer service- Molly solved problem with this harness. Best of all - she saved me over $200.00 that Nissan wanted just to diagnose problem. If I can install this, anyone can. It only took 10 minutes and I had running lights.
Thank you
This was easy, clear instructions, simple procedure
Very simple install, plug and play electrical connections, very simple to use and very good quality product. Very happy it was put on in PA on Friday afternoon and hauled a uhal trailer to GA Saturday morning. Had 0 issues. Definitely a 5 star rating
provided everything I needed and more. It was securely packaged and in mint condition. I will be able to tow my trailer legally when it's dark.

Exceptional. No problems at all.
Looks good, haven't installed it yet.
Right part for the right car. Order shipped the day I placed it, arrived earlier than scheduled. Combined with their numerous videos on installation, hard to think of a better service package out there. So easy, so simple. And for less than half what my local parts shop quoted (and didn’t have in stock)
I’ve got three emails confirming order, shipment and delivery.
I’ll be back when it’s time to wire up the Rogue.
Just what I needed. Works great.
Very easy to install worked great
Good product fast delivery

Really great, it went in easy .I had Some help ,a salamander lounged near the rear wheel .possibly in a drunken stupor..
However, we both enjoy the wiring install (how often does anyone say that.) it snapped right into place !
By the time it takes a drunken salamander to dose off ..well job done !
Everything was on time and fit like a glove. Easy tracking shipment. Well done etrailer
Easy to plug in, one in cabin and one under the hit her
Worked as intended

Would your boss say the same thing about you, Matthew? Just some food for thought...:)
It was awesome great product delivered great
I purchased a wiring kit and hitch ball for my new 2016 Nissan Frontier. The truck does not have the factory tow package. However, it does have a class-II tow bumper and Nissan sends them all pre-wired for lighting, but not activated.
The kit I ordered from etrailer had everything I needed to activate the factory wiring harness (a couple of simple, plug-in relays) and a 4-pin flat plug that also just plugged into the factory pigtail at the rear of the truck. Added a bracket for the flat plug (also from etrailer) and in about 30 minutes I was good to go.
I consider myself above average in the shade-tree mechanic stuff, but I think pretty much anyone could do this installation. It was simple and straightforward. They even have a very helpful video of the install procedure online.
Based upon this purchase, I would consider etrailer for any future purchases I may have for trailering products and their shipping was fast and well packaged too.
